Craftsman 0220 - Manual (Page 21)

• Insert a pin or lock through the hole in the locking mechanism.
• Ensure the coupler is all the way on the hitch ball and the locking mechanism is
engaged.
• Lower the trailer so that its entire tongue weight is held by the hitch. Push the
safety latch downward to a horizontal position to lock it in place.
• Pull up on the coupler to ensure it is securely fastened to the tow vehicle.
If the coupler cannot be secured to the hitch ball, do not tow the trailer.
Refer to Section 10.2.3 for information on coupling your trailer.
5.2.1.4 Rigging the safety chains
• Visually inspect the safety chains and hooks for wear or damage. Replace worn
or damaged safety chains and hooks before towing.
• Rig the safety chains so that they:
1. cross underneath the coupler;
2. loop around a frame member of the tow vehicle or to holes provided in the
hitch system (but, do not attach them to an interchangeable part of the hitch
assembly); and
3. have enough slack to permit tight turns, but not be close to the road surface,
so if the trailer uncouples, the safety chains can hold the tongue up above the
road.
WARNING
Use 30W Motor Oil to lubricate the ball and inside of coupler.
Always check ball and coupler before each tow for damaged or
worn edges. Damaged balls and couplers should be replaced
immediately. Failure to follow this warning could result in
property damage, personal injury and death.
